BD8132FV-E2 ROHM

Power Supply IC Series for TFT-LCD Panels High-precision Gamma Correction ICs with built-in DAC No.09035EBT02 BD8132FV, BD8139AEFV Description These gamma correction voltage generation ICs feature built-in DACs and provide a single-chip solution with setting control via serial communications, a high-precision 10-bit DAC, an output amp (18-channel or 10-channel), and Vcom. Features 1) Single-chip design means fewer components 2) Built-in 10 bit DAC (18ch: BD8132FV, 10ch: BD8139AEFV) 3) Built-in DAC output amp 4) Built-in Vcom amp 5) Built-in auto-read function 6) 3-line serial interface (BD8132FV) or 2-wire serial (BD8139AEFV) 7) Thermal shutdown circuit 8) SSOP-B40 package (BD8132FV) / HTSSOP-B40 package (BD8139AEFV) Applications These ICs can be used with TFT LCD panels used by large-screen and high-definition LCD TVs.
